    WebP, APNG, GIF. 19 | - Display/encode/decode still image with these types:
    WebP, PNG, GIF, JPEG, JP2, TIFF, BMP, ICO, ICNS. 20 | - Baseline/progressive/interlaced image decode with these types:

Update cocoapods to the latest version. 141 | 2. Add `pod 'YYImage'` to your Podfile. 142 | 3. Run `pod install` or `pod update`. 143 | 4. Import \. 144 | 5. Notice: it doesn't include WebP subspec by default, if you want to support WebP format, you may add `pod 'YYImage/WebP'` to your Podfile. 145 | 146 | ### Carthage 147 | 148 | 1. Add `github "ibireme/YYImage"` to your Cartfile. 149 | 2. Run `carthage update --platform ios` and add the framework to your project. 150 | 3. Import \. 151 | 4. Notice: carthage framework doesn't include WebP component, if you want to support WebP format, use CocoaPods or install manually. 152 | 153 | ### Manually 154 | 155 | 1. Download all the files in the YYImage subdirectory. 156 | 2. Add the source files to your Xcode project. 157 | 3. Link with required frameworks: 158 | * UIKit 159 | * CoreFoundation 160 | * QuartzCore 161 | * AssetsLibrary 162 | * ImageIO 163 | * Accelerate 164 | * MobileCoreServices 165 | * libz 166 | 4. Import `YYImage.h`. 167 | 5. Notice: if you want to support WebP format, you may add `Vendor/WebP.framework`(static library) to your Xcode project. 168 | 169 | FAQ 170 | ============== 171 | _Q: Why I can't display WebP image?_ 172 | 173 | A: Make sure you added the `WebP.framework` in your project. You may call `YYImageWebPAvailable()` to check whether the WebP subspec is installed correctly. 174 | 175 | _Q: Why I can't play APNG animation?_ 176 | 177 | A: You should disable the `Compress PNG Files` and `Remove Text Metadata From PNG Files` in your project's build settings. Or you can rename your APNG file's extension name with `apng`. 178 | 179 | Documentation 180 | ============== 181 | Full API documentation is available on [CocoaDocs](http://cocoadocs.org/docsets/YYImage/).
182 | You can also install documentation locally using [appledoc](https://github.com/tomaz/appledoc). 183 | 184 | 185 | 186 | Requirements 187 | ============== 188 | This library requires `iOS 6.0+` and `Xcode 8.0+`. 189 | 190 | 191 | License 192 | ============== 193 | YYImage is provided under the MIT license.
